Ubuntu sometimes freezes and I can't do nothing. I need to reboot the system pressing reset button. Usually Ubuntu (I think that Gnome-shell) freezes when I am selecting a game in Steam. When I select one game and change to another selecting the other, Ubuntu freezes. But it doesn't happen always. I read that could be a problem with Ryzen CPUs, but I don't know. Sorry and thanks for your time.
